LYNCHBURG, VA — November 15, 2017
TRAX recently completed delivery on the new high-fidelity combined cycle simulator for TVA’s Thomas H. Allen Plant. The new TVA Allen Combined Cycle Plant is a 2×1 natural gas facility with a design load of 1,100 MW that features only the second installation of GE’s latest 7HA.02 gas turbine in the United States.
The TRAX TVA Allen simulator features high-fidelity models of the 7HA.02 gas turbine, controlled with the GE virtual MarkVIe, two Vogt HRSGs, and one Toshiba steam turbine.
The simulator project was developed in parallel with the construction of the plant, and was a valuable tool in testing both the GE MarkVIe and the virtual DCS controls and HMI. GE engineers used remote testing and spent time on the TRAX test floor updating the controls with the use of the simulator. TRAX engineers and technical specialists worked closely with the control suppliers and TVA operations personnel throughout the testing phase of the project to ensure the models and controls performed as expected.
The challenging project required TRAX project management to coordinate the efforts and schedules of the DCS supplier, GE turbine controls development, Toshiba controls development, and the TVA/Kiewit construction schedule. TRAX successfully delivered the simulator ahead of first fire, providing TVA with a high-quality training tool that will last well beyond the initial benefit of controls testing during the project development.
